Chemistry of indoor aerosols

Aerosols and their chemistry are strongly influenced by the building environment. There are large temporal and spatial gradients in temperature and humidity in buildings, mechanical systems, interstitial spaces and even around occupants. The building shell and surfaces can attenuate infiltrated particle concentrations and alter the composition of particles via transfer of semivolatile compounds between surfaces and particles. Occupant activities such as cooking and cleaning can generate aerosols and modify existing aerosols. This session highlights recent advances in the chemistry of indoor aerosols as revealed by field and laboratory research as well as modeling.
